Scandlines has signed an agreement with Finland’s Norsepower Oy to install a wind rotor on COPENHAGEN, already one of the world’s largest hybrid ferries, with combined diesel and battery propulsion

The Danish-German ferry company has already invested more than €300M in building new ferries or refitting ferries with hybrid propulsion. With the additional Norsepower equipment, the ecological footprint of COPENHAGEN will be further enhanced.
The Norsepower rotor sail is a development of the Flettner rotating cylinder. Existing customers for it include Viking Line. Similarly, a Norsepower rotor sail is installed on ESTRADEN, a ferry that P&O Ferries operates between Zeebrugge and Teesport.
The technology is based on a spinning cylinder that uses the Magnus Effect to harness wind power for propulsion. Under positive wind conditions, the rotor sail can reduce the need for engine power and thus reduce emissions, without sacrificing speed.
Preparation for the installation for the rotor sail will commence this November and it will be installed during H2 2020. It will be 30m tall and have a diameter of 5m.
"With the installation of a rotor sail we can reduce CO2 emissions on the Rostock-Gedser route by 4-5%," said Soren Poulsgaard Jensen, CEO of Scandlines.
NABU, a leading German environmental protection group, has welcomed Scandlines’ initiative. Malte Siegerthead, the NGO’s head of environmental policy, said: "Scandlines is setting new standards for the integration of different technical solutions to reduce climate damage and air pollution. To meet Paris [COP 20] commitments, it is important that other shipping companies do the same."
